Development of a genetic marker panel for Grass Carp (Ctenopharyngodon Idella) to better understand reproducing populations in Lake Erie tributaries

July 2019 - June 2020


Participating Agencies

  • Upper Midwest Environmental Sciences Center

Grass carp have spread to Lake Erie, but knowledge of their spawning biology and the number of individuals that have colonized is lacking. The goal of this project is to develop genetic tools (a GTseq panel) that can be used to conduct parentage analysis of grass carp. The project is a collaboration between USGS and UW-Stevens Point. The panel will be used to analyze grass carp eggs to determine parental contributions which will inform management of grass carp in Lake Erie.
